The RingConn(R) Gen 2 redefines health tracking. It is a full-featured smart ring designed for seamless, everyday wear. The digital ring offers automatic sleep apnea monitoring to help you optimize rest and an ultra-slim, lightweight build that merges comfort with style. You also get an impressive 10 to 12 days of battery life (up to 150 days with its portable charging case), quick charging, and with our RingConn(R) EcoPower technology, we've refined optical pathways and enhanced algorithms to achieve reduced power consumption while maintaining familiar performance levels. Best of all, you'll get comprehensive monitoring with no subscription fees. Please note - before you order, be sure to review the Sizing Guide, as seen in the images section, as RingConn(R) ring sizes are different than those used in the US. Or better yet, size before you buy so you'll know for sure - order the Gen 2 Ring Sizing Kit first, sold separately.

Want to buy a RingConn(R) Gen 2 Smart Ring but you're not sure what size ring to order? Size before you buy! This is especially important since RingConn(R) ring sizes are different than others. The company has studied a large number of finger and finger bone samples and designed an irregularly shaped smart ring based on the research conclusions to ensure wearing comfort and accuracy in data collection. So, we advise you order this Ring Sizing Kit first. It contains the plastic versions of RingConn(R) Gen 2 ring sizes 6 through 14. Wear a size for at least 24 hours. It is recommended you wear it on either the index, middle, or ring finger as that is where the actual ring needs to be for optimal performance and accuracy.
